Daniel Sanders 12e6e709e9 [globalisel][tablegen] Honour priority order within nested instructions.
It appears that we haven't been prioritizing rules that contain nested
instructions properly. InstructionOperandMatcher didn't override
isHigherPriorityThan so it never compared the instructions/operands/predicates
inside nested instructions.

Fixes PR35926. Thanks to Diana Picus for the bug report.
